To all whom itmay' concern:

Be it known that I, DANIEL W. MCLEAN, subject of the Kin of GreatBritain, residing atHighland Tark, county of Wayne, State of Michigan,have invented a certain new and useful Improvement inCar-Mov ingDevices, and declare the followin to be a full, clear, and exactdescription of the I same, such as-will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

My invention relates to car moving devices operated bymeans of a handlever. The object of my invention is to provide a car moving deviceoperated by means of a hand lever, whereby downward pressure uponthehand lever not only brings lifting pressure to bear upon theperiphery of the car'wheel but at the same time securely clamps-thedevice to the rail so as to afford r a stationary non-slipping fulcrumfor such lever to act on. V

A further object of my invention is to provide-a device which will applypressure tc the periphery-of the car wheel at a point removed as far aspossiblefrom the perpendicular axisof the wheel'so as to bring to bearthe greatest possible leverage upon the wheel. In all previous devicesintended to perform like work, such as'the long used pinch bar, or itsvarious modifications, the point of pressure against the, periphery ofthe wheel was at a point well in under the wheel. The leverage developedin the wheel for a constant amount of pressure is considerably greaterin my device than would be the case if the pressure were ap- Fig. 3 is avertical sectional view taken on line 33 of Fig. 2.

CAR-MOVING DEVICE.

.PatentedDecQ, 1919.

Application filed March 1, 1919. Serial No. 279,981

Fig. 5 is a top plan view of member 3 shown in side elevation in Fig. 2.

Fig. 6 is a side view showing the application of the car mover to thecar wheel at the beginning of the forward impulse.

- Fig. 7 is a like view showing the application of the car mover to thecar wheel at the completion of the forward impulse.

Similar numbers refer to similar parts.

My device is shown in operable contact with a car wheel in Fig. l. Thepoint of pressure against the periphery of the wheel is indicated at A.Forward member 1, which is shoved well in underneath the wheel, and hasa downwardly inclined face to permit its insertionwell underneath thewheel, is loosely linked to two rearward members 2A and 213, by meansoflinks 7A and "(B as shown in Fig. 4. Said links are tongued in groovesin the ends of said forward member 1 and rearward members 2A and 2B, andpivotally fastened thereto by means of rivets orbolts as indicated at 2Cand 2D. I

The aforementioned rearward members 2A and 2B are shown as pivotedtogether by means of a bolt orrivet pin 9. The rearward ends of saidrearward members 2A and 2B are shown as provided with downwardlyprojecting clamps, preferably roughened on their inner surfaces tofrictionally grip the sides of the rail, as shown in Fig. 3. The loweredges of said clamping projections are preferably serrated, Fig. 2,which would serve a useful purpose, in case, as frequently occurs atcrossings, wooden crossing blocks were placed between the rails, theupper surfaces of said blocks coming almost flush with the top of therail, in such case the serrated edges would grip the crossing blocks,preventing abackward slipping of the device when downward pressure isappliedto the hand lever. Said rearward members 2A and 2B are'providedwith lugs or short standards 2A and 213 respectively screwed therein.Said short standards 2A and 213' support by means of a double toggle,fulcrum member 4:. Said double toggle consists of two pairs of links,numbered as 6A, 6B, and 6D (6D not being shown in the drawings, butforming the other and opposite link of the pair of which 6C is amember). Said fulcrum member 4 is pivotally fastened by means of a boltor connecting pin 613 to the inner ends of said links constitutingthedouble toggle, as shown in Fig. 3. The outer ends of said linksforming-the double toggle, are pivotally fastened as shown in-Figs. 2and- 3 to said'sho'rt standards 2A and 2B,,v

The device is operated by means of hand which is pivotally pp ed bfulcrum member 4:, witlrwhichit is con neoted by means of a connectingpin or bolt 4A as shown in Fig. 3. The forward end fastened by means ofa bolt or pin 3B to the forward end'of said hand lever 5;

The method of operation is-as follows: The device being placed on therail, indicated at 11, the forward member 1 is inserted well under carwheel 10, the handle 5 being in an elevated position. By virtue ofhandle 5 being well elevated, the inner ends of said connecting linksconstituting the double toggle are raised well up. It will be noted thatthe short standards 2A- and 213 to which such double toggle is fastenedare somewhat forward of the point 9 where said rearward members are joined together; therefore a lifting of said toggle links will draw theforward ends of said rearward members 2A and 2B toward each other,spreading the rearward ends of the same members apart and allowing thedownwardly projecting clamps on said rearward ends to, fit down oneither side of the rail. When pressure is first applied to said handlever 5, the toggle links are flattened out by the downward pressure ofsaid fulcrum member 4;, the forward ends of said rearward membersthereby being forced away from each other, bringing the rearward endswith their downwardly projecting clamps toward each other and clampingthem against the side of the rail. This affords a permanent non-slippingfulcrum for the hand lever to work on. Continued downward pressure onthe long arm of the hand lever, with its consequent elevation of theshort arm of said lever, forces the upper extremity of the connectinglink 3, which is pivoted at 3B to said hand lever, against the peripheryof the car wheel at A, rotating the wheel and propellin the car forward.The device is loosened from the rail byelevat: ingthe handle 5; and itcan then be pushed forward, preferably with the foot, and the operationrepeated.

7 It will be seen that this device possesses two distinct advantagesover apparatus reviously devised to perform like work. irstly, that thedownward motion of the hand lever whichbrings pressure to bear upon thecar wheel, also locksr device uponthe rail thereby preventing anybackward slipping of the'device ;thns maintaining a stationary fulcrumon which: the

lever can operate.-- Secondly,that the pressure polnt upon theperipheryof the wheel,

is no'l'o'nger a point almost directly. underneath the perpendicularaxis ofthe wheel, but the pressure is applied at a polnt'suifrcientlyremoved from the perpendicular axis of the wheeltosecurethegreatestleverage, thus enablingthe same amountfofiwork to beperformed with the expenditure of but a fraction of the effort necessarywhen "the point of application -c f ypressure to. the "pee riphery ofthe carwheel more nearly a'pproaches the projectionof the perpendicularaxis on the lower surface ofthe wheel.,f

What I'claim is: I V 1. Ina car mover, in combinat on with two pivotallyjoined gripping members of a j forward member loosely connected 1therewith and adapted to impinge underneath the car wheel, a bearingmember pivoted for ro',

4. In a car moving device,'in combination with two pivotally connectedgripping members adapted to grip opposite sides of a railway rail, ahand lever fulcrumed above and forward of their pivotal point, meansjoining said gripping members together forward a of their pivotal axis,said means supporting said hand lever so adapted that downward pressurethereon operates laterally said gripping members, a bearing membercarried at the forward end of said hand lever, a forward memberpivotally carried at the lower end of said bearing member rearwardlyloosely connected to said gripping members and adapted to impingeunderneath the car wheel.

In testimony whereof I sign this specification. V
